Grant managed two birdies on the round but with three bogeys and a double on her card she posted a three-over-par 75 to move up into a share of 28th spot at nine-over-par.
Ballinrobe’s Shannon Burke, who played alongside Grant at the Home Internationals in Ballybunion last August, is next best despite returning a round of 80 this afternoon. Burke finds herself in a share of 60th spot at 16-over with a round to go at Montado.
Woodstock’s Aine Donegan posted an 80 of her own to fall to a share of 74th on +20. Grange’s Elisa Corcoran fired her third 82 in succession for a +30 total while Hermitage’s Ciara Casey also returned an 82 to sit a shot further back at +30.
At the top, England’s Isobel Wardle and France’s Lucie Malchirand lead the way at three-under-par.
